RErnacrorw BURNER.

' same.

This invention relates to improvements in gas burners and embodies as its mam feature a novel radlant member through which the gas passes and in which combustion takes place. .The various features of novelty and invention'will appear from the detailed description taken in connection with the accompanying drawings and are intended to be set forth in the appended claims.

In the drawings-.5

Figure 1 is a vertical section through a furnace door illustrating the construction and application of the present invention.

Figure 2 is a front elevation of the gas manifold and'supply pipes removed from the furnace.

Figure 3 is a fragmentary view of the improved refractory burner in association with the gas supply pipes.

Figure 4 is a fragmentary plan view of a modified form of the refractory burner.

1 indicates a door frame set in a furnace opening, said frame having a transversely extending member 2, constructed with two parallel passages. 3 and 5. A gas supply pipe 8 is adapted to pass slidably through the orifice 3, and to e adjustably'secured therein as by set screw 4. A door or damper 7 is slidably mounted upon the gas supply pipe 8, and has a guide rod 6 adapted to pass through the orifice 5 of member 2 to maintain the door in the proper alignment with the door frame 1..

Upon the inner end of the main gas supply pipe 8 is a vertical manifold pipe 9, upon which and in communication with which are a plurality of spaced horizontally disposed subordinate gas supply pipes 10 which are provided upon thelr rear faces with a plurality of' spaced discharge openings 11.

Disposed in front of the pipes 10 is a frame 14 having a flange 12 which is outwardly' beveled as at 13 to readily receive a radiant member 16 of refractory material.

This radiant member has extending therethrough a lurality of orifices or openings 17 of peculiar shape, and the upright wall of the frame 14 is provided with corresponding registering openings therethrough. In

cross-section the openings 17 are preferably in the form of a Greek cross, the arms there of constituting gas ports 18, 17 and 18' representsopenings and parts of a modified form,'said ports and the openings 11 in the gas pipes 10 being so arranged with respect to each other that the jet of gas issuing through a jet or pipe opening 11'will enter the ports 18 as distinguished from the main orifice 17 of which the ports are a part. Each gas jet will, therefore, be flanked on all sides but one by the hot surface of the radiant member. ,The air necessary to support combustion is drawn into the ports 18 and the orifices 17 by the jets of gas issuing from the jet openings 11 in the pipe 10. Thorough mixing of the gas and air is therefore obtained and the gas is ignited before it leaves the radiant member. Due to the hot radiant material surrounding all of the gas jets, a more perfect combustion is obtained than is ordinarily procured. The radiant member is made of a refractory material and will withstand high temperatures and the depth of the same issuflicient to prevent the frame 14, which is of cast iron, from becoming unduly hot. The depth of the radiant member is also such that the as and air drawn in by the jets of gas wil become thoroughly mixed before final discharge from the radiant member. In operation the radiant member becomes a bright red, and the fuel becomes ignited in'its passage through the openings or orifices in the radiant member.

Various modifications in the precise form' and construction of parts will readily suggest-themselves to those skilled in the art but within the scope of the present invention as claimed. 1 Having thus described my invention, I claim:
